André Araujo at AUSOUG National Conference

t’s only one week to go now and the program for the AUSOUG National Conference Series 2009 is out. I’ll be presenting on the first day in Perth (Nov 10th) about Oracle Flashback technology. I’m looking forward to attending the conference in Perth, not only because I’ll be presenting there but also because it’s my first time in Western Australia.

Running querys against multiple SQL Server AND Oracle instances

Before SQL Server 2008, there was no native support for running the same query against multiple instances using shipped tools, so it can be approached in one of these ways…I’ve used nearly all of them, but I have found that linked servers provide a higher degree of control on the target servers, error handling, and most important, the ability to use SQL server Encryption to store the credentials of source servers if some of the servers are using SQL authentication.

Gerry Narvaja: the Winds Of Change

For very personal reasons that don’t belong in this article, I decided a few weeks ago that it’s time for me to move on. The year and a half that I worked for Pythian have been a wonderful experience, and this is article is my tribute to this great company.

MySQL and Hardware Information

People often ask “what’s the best hardware to run a database on?” And the answer, of course, is “it depends”. With MySQL, though, you can get good performance out of almost any hardware. If you need *great* performance, and you have active databases with a large data set, here are some statistics on real life databases — feel free to add your own.

UKOUG Conference Tech & EBS 2009 — The Place to Be!

Yes, it’s almost that time of the year when one of the best Oracle conferences in the world opens its doors to attendees in Birmingham — UKOUG Conference 2009: Technology & E-Business Suite. The lineup of speakers will be fantastic as usual and agenda is full of juicy bits — You will have usual troubles scheduling sessions to attend and hate to make compromises between presentations you want to see badly but that’s kind of problems you’d rather have at a good conference.

MySAR, a Sidekick for Other Monitoring Tools

What Was Going On Around 2:30pm? This is a question a customer asked us. To answer it we ran MySAR for a few days and queried the results for analysis. Looking at the data, we determined that the number of INSERT operations was significantly higher than any other, so we queried for the Com_insert status values. Com_insert is a counter that accumulates the number of INSERTs issued since the last server start (or since the last FLUSH STATUS command). For details on the variables available check Chapter 1. mysqld Options/Variables Reference.

Video and Slides: How InnoDB works

This presentation was done by Sheeri Cabral of The Pythian Group and went into how to use SHOW ENGINE INNODB STATUS to get more information about your Innodb tables, foreign keys and transactions. This is a great presentation to learn how InnoDB works.

Logs Go Un-Buffered Worldwide

I regret to say, there is no Log Buffer this week, as we’ve all been busy preparing for the Big New Thing coming in a few days. The good news is, we have a Big New Thing coming in a few days. Stay tuned for that, you won’t want to miss it.
